ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 1E19 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects USP7. It targets an epitope within 15 amino acids from the N-terminal region.

KLH-conjugated linear peptide corresponding to 15 amino acids from the N-terminal region of human Ubiquitin carboxyl-terminal hydrolase 7 (USP7).

Ubiquitin carboxyl-terminal hydrolase 7 (UniProt: Q93009; also known as EC:3.4.19.12, Deubiquitinating enzyme 7, Herpesvirus-associated ubiquitin-specific protease, Ubiquitin thioesterase 7, Ubiquitin-specific-processing protease 7, USP7) is encoded by the USP7 (also known as HAUSP) gene (Gene ID: 7874) in human. USP7 is a widely expressed deubiquitinating enzyme that erases ubiquitin and protects substrate protein from degradation. It displays a preference towards lysine 48-linked ubiquitin chains. It contains an N-terminal poly-glutamine stretch (poly Q), the tumor necrosis factor receptor- associated factors (TRAF) domain (aa 62-205), the catalytic domain (aa 208-560), and the C-terminal tandem ubiquitin-like (Ubl) domain (aa 560-1102). Full activity of USP7 requires the C-terminal Ubl domain that fold back onto the catalytic domain, allowing the remodeling of the active site to a catalytically competent state by the C-terminal peptide. The catalytic domain has a three-domain architecture, including Fingers, Palm, and Thumb domains. 19 residues in the C-terminal region (aa 1084 1102), which are conserved across species are reported to stabilize the ubiquitin binding conformation of the catalytic domain. Individual point mutations at isoleucine residues 1100 or 1098 are able to abolish its deubiquitinase activity. USP7 is known to deubiquitinate multiple target proteins, including FOXO4, p53, DNMT1, PTEN, and DAXX. By preventing the degradation of p53/TP53, it enhances p53/TP53-dependent transcription regulation, cell growth repression, and apoptosis. Overexpression of USP7 has been reported in prostate cancer. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
